ABSTRACT:
An electric switching circuit with a first current path for operating an electric motor and with a second current path for operating a first heater. The electric motor drives a fan during which an air flow created by the fan is heated by the first heater. A switch for opening or closing the second current path in response to an actual operating state of the electric motor is, in the second current path, connected in series to the first heater. The switch is designed as a bimetallic switch and a second heater is assigned thereto that is arranged and designed for detecting the actual operating state of the electric motor and for controlling the bimetallic switch by changing its ambient temperature in response to the detected operating state.
